Materializes a free Cabgo workspace for the operator and queues an Android build of their branded app. No payment, no card, no checkout — the workspace is free to create and operate. Call ONLY when the user explicitly wants to create / launch / spin up / set up a new app for their business — verbs like 'create', 'launch', 'build me', 'set up an app for'. Do NOT call this for setup / installation / connector questions (use cabgo_install_instructions). Ask the user 2 things: (1) what type of business — taxi / food delivery / gas distribution? (2) what brand name for their app? Optionally city + brand color. The connected OAuth user becomes the owner automatically — no email or name is needed in the body. A single user can own multiple tenants — calling this again creates a NEW workspace rather than erroring. Branding tweaks happen via other Cabgo tools after creation. Any plan / billing / subscription management is done by the operator on https://www.cabgo.app — never through this tool.
